UCSF Benioff Children's Hospital San Francisco also formally affiliated with Children's Hospital Oakland earlier this year. The Oakland hospital was renamed UCSF Benioff Children's Hospital Oakland earlier this month after philanthropists Lynne and Marc Benioff donated $50 million to it. The San Francisco children's hospital also received $50 from the San Francisco couple.

"We're pleased that babies who require a higher level of care can be treated locally by specialists from UCSF, an institution with a reputation for providing some of the best neonatal care in the country," said Nancy Farber, Washington Hospital Healthcare System chief executive officer, in a news release.
